If you saw the previews of this week's episode of Law & Order, you know that it's Jesse L. Martin's last show. The NBC promo implies that Detective Ed Green has gotten into major trouble and will be brought up on charges for his actions, perhaps lose his badge. That would be a very dramatic way to wrap up his nine years on Law and Order, and unlike the near-fatal shooting his character survived a couple of years ago, it leaves open the door for a guest stint down the road. But not too soon. Jesse L. Martin is in talks to star in a Broadway version of Guess Who's Coming to Dinner, taking on the Sidney Poitier role.
